"Since the mouse is symmetrical, the ergonomics aren't perfect, but it does a bang up job of fitting your hand for something that tries to fit both the right and left-handed. The whole mouse, from front to back, is in an arch shape, with indents in either side for your thumb and pinky. This design is ideal, as your hand rests on the mouse with a natural feel. Overall, while the design of the mouse may not be the absolute best out there, I think Microsoft succeeded in creating a mouse that is accessible to everyone."
